摘要孕妇感染流感所带来的疾病负担是一项重要的公共卫生议题，不仅会直接威胁孕妇自身健康，还会经由母婴传播等途径对胎儿及新生儿的健康状况造成不良影响。尽管孕妇是流感疫苗接种的优先推荐群体，但在实际推行过程中，受心理机制、社会文化因素及政策执行层面障碍等多重因素影响，孕妇群体对流感疫苗的接种意愿普遍不高，进而导致接种率处于极低水平。因此，构建一套基于行为转化理论的个人—社会—政策三个维度的全方位、多层次的精准化策略体系，对于提升孕妇接种意愿并促使其将意愿转化为实际接种行为具有不可忽视的重要意义。未来，我们将以更深入、系统、全面的视角评估策略成效，探究其在不同干预策略协同作用以及多样化目标人群中的适配性，进而拓展公共卫生服务的覆盖广度，增强服务的精准程度与深度内涵，以此推动公共卫生事业沿着精准化、高效化的路径稳健发展，为全人群健康提供坚实有力的保障。

abstractsThe disease burden caused by pregnant women contracting influenza is an important public health issue, which not only directly threatens the health of pregnant women themselves, but also has adverse effects on the health of fetuses and newborns through mother-to-child transmission and other means. Although pregnant women are the preferred group for influenza vaccination, their willingness to receive the vaccine is generally low due to multiple factors, such as psychological mechanisms, socio-cultural factors, and policy implementation barriers in the actual implementation process, resulting in an extremely low vaccination rate. Therefore, building a comprehensive and multi-level precision strategy system based on the behavior change mechanism in the three dimensions of individual-society-policy is of great significance for enhancing pregnant women′s willingness to receive vaccinations and promoting their conversion of willingness into actual vaccination behavior. In the future, we will evaluate the effectiveness of strategies from a more in-depth, systematic, and comprehensive perspective, explore their synergistic effects in different intervention strategies and their adaptability in diverse target populations, thereby expanding the coverage of public health services and enhancing the accuracy and depth of services, aiming to promote the steady development of public health along the path of precision and efficiency, and provide solid and powerful guarantees for the health of the entire population.
